IMPRVEMENT IN GLASS-HOUSE POTS.

The Schedule referred to in these Letters Patent and makingv p'art of the same.

To all whom Ait may concern:

Be it known thatl, lnoMAs ScAxLAN, of Birmingham, in the county of Huntingdon, and Stute of Pennsylvnuin, have invented zt newl :md improved Gloss-House Pot; and I do hereby declare thnt.the

following is e full, clem', and exnct description of the construction :md operation of the sinne, reference being had to. the. ,accompanying drawings, making e pnrt of this speoilienton, in which my invention isrepresented by zrlougitudiunl vertical section.

' .lhe object ofY this invention is to provide, for the use of gl:iss-manuttcturers, n pot or crueihle in which to prepare the gloss, so construct-ed :md operating that it will produce more glass to n filling than those heretofore employed, and do its 'work in less time zuid with greater convenience.

A represents the body ot' the pot or Crucible; it being of such :i form thntits longitudinal section is elliptical, while its vertical section shows t-he side walls straight :md vel-tieni, the bottom tint nud horizontal, land the top n low, lint dome, or arch, I.

Nein' the upper edge of onefside \v:1.ll,(or,more. properly, end wztll,) it is provided with-two months, c c', with projecting lips, one mouth bciugzurouged vertienlly over the other, folconvenience in tilling the. pot 'in the furnace. v

The upper month c comes 'exactly' nt the. npperedge of the vertical well, and the lower mouth, e', is innuediately under it, seperated only by a. very nm'rowledge, the'lower month it-selfheiug in the glass-pots of ordivhunny size, tweuty-iour-- inches from the hottonrof the l pot, and being entirely above' the middle of thc side wall.

I :un awa-re that n pot has heretofore been inode, having two months, one nt the upper edge and one at the lower edge of the` side woll. Such construction differs umterially from mine, both in' appearance and in the proeticzrl workingof the pot, and I lay no claim to such construction. nor to any two-month pot iu which the lower mouth is helow the. middle ot the Side wnll.

That l cla-im :is new, :ind desire to secure h v Letters Potent, is-

In n pot ororncihle for nmking gloss, having the hod v A mude of tire-c-laiy und provided withn coucnve roof, '1, and mouth e, of usunl form and construction,

the additional mouth e', formed immcdinteh` under the mouth e, :md :there-the middloline of the side wall, substantially :is described.
